4 Claims.

The present invention relates to shavers of r the type having 'an outercuttinghead provided with spaced hair-receivingopenings and an innercutter for shearing hair projecting through the openings. In'suchshavers only part of the cutting head is open toreceive hair, and toperform a thorough shaving operation it is necessary that the userrepeatedly move, the head back and forth over the skin surface.-

The object of my invention is to provide an improved shaver in which thecutting head is given a. power operated scanning movement so as toexpose all-parts of the skin surface be-f heath the cutting head to theshaving" action.

For a consideration of what I believe novel appended thereto. 7 I

Inaddition to the shaving which takes place at the center of the cuttinghead, there is also a clipping action due to the movement of -.thecutting head relative to the combs 29. This clipping action clips theouter ends of the hair so the shorter lengths will be more readilyshaved.

1; In a shaver, spaced skin-gripping members, a cutting head betweensaid members having an -outer skin-engaging surface and an innershearing surface, hair-receiving openings in said head,

means for effecting a slow speed relative movement between the head andthe gripping members whereby thhair-receiving 'openings'scan the skinsurface between the gripping members, and a high speed'cuttercooperating with the inner surface of the head toshear hair project ingthrough said openings." e f 2. In a shaver, an elongated skin-grippingmember, an adjacent cutting head having an outer skin-engaging surfaceand an inner shearj ing surface, hair-receivingopenings in said head,

means for effecting the slow speed relative movement between the headand the gripping member, both lengthwise and transverse to the grippingmember whereby the hair-receiving openings scan the skin surface held bysaid gripping member, and a high speed cutter cooperating with the innersurface of the head to shear hair projecting through said openings.

3. In a shaver, an elongated skin-gripping member, an adjacent cuttinghead having an outer skin-engaging surface and an inner shearingsurface, hair-receiving openings in said head, slow speedeccentricscooperating with the head to move it lengthwise and transverseto the gripping member whereby the head scans the skin surface held bysaid gripping member, and a high speed cutter cooperating with the innersurface of the head to shear hair projecting through said openings.

4'. In a shaver, an elongated cutting head having an outer skin engagingsurface, an elongated skin gripping member having spaced teeth defininghair receivin openings,the outer surfaces of the teeth being arranged togrip the skinandthe inner surfaces of said teeth overlapping and bearingagainst part of the outer surface of the cutting head, means foreffecting a slow speed movement of the cutting head relative to thegripping member whereby the part .of the outer surface of the cuttinghead engaging the teeth of the gripping member is effective to clip hairreceived in the openings between the teeth and the remaining part of theouter surface of the cutting head scans the skin surface held by saidgripping member, and a high speed cutter cooperating with the innersurface of the cutting head to shear hair projecting through theopenings in said remaining part of the head.
